Precautions

Your doctor will check your progress closely while you are receiving this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to receive it. Blood tests may be needed to check for unwanted effects.

Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment and for 2 months after the last dose of this medicine. If you think you have become pregnant while using the medicine, tell your doctor right away.

This medicine may cause a rare but serious type of an allergic reaction called an infusion reaction. This can be life-threatening and require immediate medical attention. Tell your doctor right away if you or your child start to have cough, trouble breathing, hives, itching, or skin rash, lightheadedness, dizziness, or fainting, tightness in the chest, or swelling of the face or lips.

Check with your doctor right away if you or your child are having burning, numbness, tingling, or painful sensations in the arms, hands, legs, or feet. These could be symptoms of a condition called peripheral neuropathy.

Tell your doctor right away if you or your child have a cloudy urine, change in the amount of urine, fainting or lightheadedness, nausea, stomach pain, or swelling of the hands, ankles, or feet after receiving this medicine. These may be symptoms of a rare but serious condition called capillary leak syndrome.

This medicine could lower your blood pressure too much and cause you to feel dizzy or lightheaded. Stand or sit up slowly if you are dizzy. Low blood pressure is more likely to happen when you begin to use the medicine.

This medicine may cause reversible posterior leukoencephalopathy syndrome (RPLS). Tell your doctor if you have severe headache, changes in vision, fast, pounding, or uneven heartbeat, seizures, unusual drowsiness, dullness, tiredness, weakness, or feeling of sluggishness.

Check with your doctor immediately if blurred vision, difficulty in reading, or any other change in vision occurs during or after treatment. Your doctor may want you or your child to have your eyes checked by an ophthalmologist (eye doctor).

Dinutuximab can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take, especially when your blood count is low, to reduce the risk of infection or bleeding:

Tell your doctor right away if you or your child have black, tarry stools, blood in the urine, fever, increased or decreased urination, pinpoint red spots on the skin, stomach pain, swelling of the face, fingers, feet, or lower legs, unusual bleeding, bruising, or weakness, or yellow eyes or skin after receiving this medicine. These may be symptoms of hemolytic uremic syndrome.
